A Guide to Choosing the Right Water Heater
A water heater is a basic necessity for every household.
A water heater is one of those essential home appliances that most people don’t think about until it stops working. Yet, it’s responsible for delivering the comfort and convenience of hot water for showers, laundry, dishwashing, and cleaning—day in and day out. Selecting the right water does not mean picking a model from the shelf; it involves understanding the household’s needs, energy efficiency goals, and the long-term value of your investment. As professional plumbers, we know how important it is to make an informed decision, and we’re here to guide you through the process with clarity and confidence.
Understanding the importance of the right water heater
A water heater typically lasts between 8 and 12 years, making it a long-term investment in your home’s comfort and efficiency. It also accounts for a significant portion of your monthly utility bills—sometimes as much as 20 percent. That’s why choosing the right water heater is not just about immediate needs but also about future savings, reliability, and peace of mind.
Modern water heaters come in various types, sizes, and fuel options. With so many choices, it can be overwhelming to know where to start. This water heater buying guide will walk you through the main types of water heaters, the key factors to consider, and how professional installation ensures optimal performance and safety.
Types of water heaters
The first step in choosing the right water heater is understanding the available types. Each type has its advantages, limitations, and ideal applications. Here’s a closer look at the main options:
Storage water heaters
Storage water heaters are the classic choice and remain the most common type in homes today. They feature an insulated tank that stores a set amount of hot water—usually between 20 and 80 gallons—ready for use whenever needed. They run on natural gas, propane, oil, or electricity.
The main advantage of a storage water heater is its simplicity and relatively low upfront cost. However, they experience standby heat loss, meaning they use energy continuously to keep the water hot, even when you’re not using it. This leads to higher operating costs over time. Storage water heater installation is straightforward for most homes, but selecting the right size is essential to avoid running out of hot water or wasting energy.

Tankless water heaters
Tankless water heaters, also known as on-demand water heaters, have become increasingly popular in recent years. Instead of storing hot water, they heat water instantly as it passes through the unit. This means you’ll never run out of hot water if the unit is sized correctly for your household’s needs.
Tankless water heater types include electric and gas models in various capacities. These units are highly energy efficient, eliminating standby heat loss, and they take up much less space than storage tanks. However, the initial cost is higher, and larger households may require multiple units to meet simultaneous hot water demands. Proper hot water heater installation is critical for tankless systems, as water flow rates and fuel supply must be carefully matched.
Heat pump water heaters
Heat pump water heaters are one of the most energy-efficient options available. Rather than generating heat directly, they use electricity to move heat from the air or ground into the water. This process can be two to three times more efficient than conventional electric water heaters.
Heat pump models are best suited for climates with moderate temperatures and require a certain amount of space for air circulation.While the upfront investment is higher, the long-term savings on energy bills can be substantial. These systems are ideal for homeowners willing to reduce their carbon footprint and energy costs.
Solar water heaters
Solar water heaters harness the sun's power to provide hot water. There are two primary types: active systems, which use pumps to circulate water, and passive systems, which rely on natural convection. Solar water heaters are especially effective in sunny climates and deliver significant energy savings over time.
However, these systems require a larger initial investment and may need a backup heating source for cloudy days or high-demand periods. They also need adequate roof space for solar collectors. If you’re interested in renewable energy solutions, a solar water heater is a forward-thinking choice that can pay off in the long run.
Key factors to consider when choosing a water heater
With so many options available, how do you choose the best water heater for your home? Here are the key factors to keep in mind:
Fuel options
The fuel type available in your area influences the water heater choices. Common fuel sources are natural gas, propane, oil, and electricity. Each has pros and cons regarding cost, efficiency, and environmental impact. For example, natural gas heaters often have lower operating costs than electric models but may not be available everywhere. Selecting the right water heater often starts with determining which fuel options are accessible and cost-effective for your home.
Water heater size and capacity
Proper sizing ensures comfort and efficiency. A water heater that’s too small will leave you with cold showers, while one that’s too large will waste energy heating water you don’t use. The right size depends on the type of heater, the number of people in your household, and your peak hot water usage.
Professionals calculate the required capacity for storage water heaters based on the number of bathrooms, appliances, and simultaneous hot water needs. For tankless models, the flow rate (measured in gallons per minute) must match your household’s maximum demand. A professional plumber can assess your needs and recommend the best size.
Energy efficiency
Many homeowners prioritize energy efficiency for environmental reasons and to save money on utility bills. Look for the Energy Star heater label when shopping for a new unit. Energy Star tankless water heaters and storage models meet strict efficiency standards set by the Environmental Protection Agency, often qualifying for rebates and incentives.
Comparing the energy factor (EF) or uniform energy factor (UEF) ratings can help you understand how efficiently a water heater converts energy into hot water. Higher ratings mean lower operating costs over the unit's lifetime.
Installation requirements and costs
Proper hot water heater installation is essential for safety, performance, and warranty protection. Professional installation ensures the unit is correctly connected to your plumbing and electrical or gas systems, vented safely, and set up for optimal efficiency. Some water heaters, such as tankless and heat pump models, have specific installation requirements that must be met for the system to function properly.
Installation costs can vary depending on the job's complexity, the type of heater, and any modifications needed to your home’s plumbing or electrical systems. A professional plumber will provide a detailed estimate and explain the installation process so there are no surprises.
Maintenance and longevity
Different types of water heaters have different maintenance needs. Storage water heaters may require periodic flushing to remove sediment buildup, while tankless units need descaling to maintain efficiency. Heat pump and solar systems have their maintenance routines. Regular professional maintenance extends the water heater's life and keeps it running efficiently.
Most water heaters last 8 to 12 years, but high-quality models with proper care can last even longer. When selecting the right water heater, consider the expected lifespan and the availability of replacement parts or services.
Cost considerations
While it’s tempting to focus on the upfront price, it’s important to consider the total cost of ownership, including installation, energy use, maintenance, and potential repairs. Sometimes, paying more for a high-efficiency or Energy Star tankless water heater can result in significant savings over the years. A professional can help you compare options and calculate the long-term value of different models.
Why professional guidance and installation matter
Choosing and installing a water heater is not a one-size-fits-all process. Every home has unique needs, and every water heater has specific requirements. Professional plumbers bring expertise, experience, and the right tools to ensure your new water heater is sized, installed, and maintained correctly.
